Three-dimensional holographic ring traps
We describe a class of diffractive optical elements intended for use in holographic optical trapping systems that project ring-like optical traps. Unlike optical vortex traps, which carry orbital angular momentum, these ring-like traps implement a force-free one-dimensional potential energy well for micrometer scale objects. Also unlike most optical vortices or ring-like Bessel beams, these rin...
متن کاملCritical exponents for the three-dimensional superfluid-Bose-glass phase transition.
The critical phenomenon of the zero temperature superfluid−Bose-glass phase transition for hard-core bosons on a three-dimensional disordered lattice is studied using a quantum real-space renormalization-group method. The correlation-length exponent ν and the dynamic exponent z are computed. The critical exponent z is found to be 2.5 for compressible states and 1.3 for incompressible states. Th...
متن کاملPersistent Current of a One-Dimensional Wigner Crystal-Ring
We calculate the magnetic moment (‘persistent current’) in a strongly correlated electron system — a Wigner crystal — in a one-dimensional ballistic ring. The fluxand temperature dependence of the persistent current is shown to be essentially the same as for a system of non-interacting electrons. In contrast, by incorporating into the ring geometry a tunnel barrier, that pins the Wigner crystal...
متن کاملThree Dimensional Computational Fluid Dynamics Analysis of a Proton Exchange Membrane Fuel Cell
A full three-dimensional, single phase computational fluid dynamics model of a proton exchange membrane fuel cell (PEMFC) with both the gas distribution flow channels and the Membrane Electrode Assembly (MEA) has been developed. A single set of conservation equations which are valid for the flow channels, gas-diffusion electrodes, catalyst layers, and the membrane region are developed and numer...
متن کاملA three-dimensional multiscale model for gas exchange in fruit.
Respiration of bulky plant organs such as roots, tubers, stems, seeds, and fruit depends very much on oxygen (O2) availability and often follows a Michaelis-Menten-like response. A multiscale model is presented to calculate gas exchange in plants using the microscale geometry of the tissue, or vice versa, local concentrations in the cells from macroscopic gas concentration profiles. This approa...
